re: Did out of bounds Bama player have to reestablish himself to become a legal participant

First, its clear that the fingers of his hand are not curled around the ball. Only the thumb and pinkie are in contact with the ball. The fingers are still extended like a high five. That is not possession

Second, by the time he wraps his fingers to establish said possession, the Bama player has already swatted and dislodged the ball. The instant the ball shifts, its dead, because Bama is out of bounds. So possession was never established
